2913 メカニカルアロイング粉末を用いて表面改質したマグネシウム合金の摩耗特性(S34-1 粉末成形とその評価(1),S34 粉末成形とその評価)
詳細
Aluminum powder was mixed to magnesium alloy (AZ31) machined chip with various contents and then mechanically alloyed (MA) for 54ks. The obtained MA powders bonded to AZ31 rod by compressive deformation for improvements of wear and corrosion properties. Friction and wear properties of MA alloy surface were investigated and they were compared with AZ31 alloy. Ring of quench-hardened steel (SKD-11) was slid on bonded MA alloy surface under various conditions of sliding speed and normal force using ring-on-disk type wear tester. Wear loss (worn volume) in the MA alloy surface decreases with increasing of Al content. The wear loss of Mg-61.5mol%Al MA alloy surface reached to one third of that of AZ31 alloy.
